How to fix?

There is no fixed version for RHEL:10 kernel-rt-debug-modules-core.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug-modules-core package and not the kernel-rt-debug-modules-core package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

xfs: don't walk off the end of a null sc->sa.agi_bp in AGI repair

LOLLM noticed a longstanding bug where xrep_iunlink_walk_ondisk_bucket tries to walk ragi->sc->sa.agi_bp to rebuild the unlinked inode lists. Unfortunately, it's possible for agi_bp to be null if the buffer verifier fails, so we have to use ragi->agi_bp (which skips verifier checks) instead.
